Skidproof structure for container

ABSTRACT

A skidproof structure for containers includes at least one slot disposed on bottom of a container and at least one skidproof member whose shape corresponds to shape of the slot mounted into the slot. A plurality of separated projecting parts with the same height is integrated with the lower surface of the skidproof member that contacts with table surface. Thus the skidproof member contacts the table surface by the projecting parts so as to reduce contact area and adhesion force between the skidproof member and the table surface.

BACKGROUND OF THE INVENTION

The present invention relates to a skidproof structure for containers,especially to an integrated skidproof member having a pluralityprojecting parts with the same height on lower surface thereof thatcontacts a table surface. Thus the skidproof member achieves goodskidproof effect yet won't attach on the table surface.

Containers such as bowls, cups, dishes, pots or barrels are essentialsfor daily lives. There are various shapes and sizes of containers. Inaccordance with different uses, containers are made from differentmaterials including plastic, resin such as melamine with good thermalstability and luster, clay, ceramic, or metal such as stainless steel oraluminum alloy. In order to make the containers set stably on a flat andsmooth plane such as glass surface without sliding freely, at least oneslot is disposed on bottom of the container. There is no limit on numberand shape of the slot. It can be a ring, a strip or a piece. Then askidproof member with shape corresponding to the slot is mounted insidethe slot. The skidproof member is made from skidproof material such asplastic, rubber or silicon and is extruding outwards the slot,contacting with the table surface. However, conventional skidproofmember contacts the table by a plane so that when it receives the weightof the containers (utensils) and presses on the table, it attaches thetable surface tightly. Thus adhesion force between the contact area ofthe container and the table surface is increased. This brings userstrouble because it's difficult to pick up the container. Once users pickup the container with a larger force, the container may turn over andthings therein are pouring out. The skidproof member may even separatewith the container or the table is damaged. Therefore, there is still aspace for improvement of the skidproof member.

SUMMARY OF THE INVENTION

Therefore it is a primary object of the present invention to provide askidproof structure for containers that consists of at least one slot onbottom of the container while a skidproof member in shape correspondingto shape of the slot is mounted inside the slot. Moreover, a pluralityof integrated projecting parts with the same height, separated with oneanother, is disposed on lower surface of the skidproof member. Thus thebottom of the container contacts with the table by the projecting partsso that contact area and adhesion force between the skidproof member andthe table surface are reduced. Therefore, the skidproof member not onlyhas skidproof effect but also prevents attachment of the container onthe table surface.

It is another object of the present invention to provide a skidproofstructure for containers that includes projecting parts. The number,shape and interval of the projecting parts are not limited. The shape ofthe projecting parts can be a curved surface or a semisphericsemispheric. The projecting parts are uniformly distributed over theskidproof member so that the container is put on the table stably by theprojecting parts.

DETAILED DESCRIPTION OF THE PREFFERED EMBODIMENT

Refer from FIG. 1 to FIG. 5, a container (or utensil) 1 according to thepresent invention includes bowls, cups, dishes, pots or barrels. Thereis no limitation on material of the container 1, it can be plastic,resin, ceramic, metal or combinations of above materials while melaminewith good thermal stability and luster is preferable. Moreover, there isnot limitation on appearance of the container 1 or shape of the bottom10. For example, the container 1 may have a round opening and a roundbottom, as shown in FIG. 1, or have an oval opening, a rectangularopening in combination with a rectangular bottom, as shown in FIG. 6.The openings and the bottom can be irregular shapes. In order to offerideal skidproof protection while being put on the table, at least a slot11 is arranged on the bottom 10 of the container 1 while there is nolimitation on the shape and number of the slot 11. It can be circular,as shown in FIG. 2, FIG. 7 & FIG. 11, like a bar, as shown in FIG. 9 &FIG. 10, or sheety, as shown in FIG. 8. Then a skidproof member 2 withcorresponding shape is mounted into the slot 11. For example, askidproof ring in FIG. 2, FIG. 7 & FIG. 11, a straight skidproof bar inFIG. 9, a L-shaped skidproof bar in FIG. 10, or a skidproof sheet inFIG. 8. The lower surface of the skidproof member 2 projects outwardsthe opening of the slot 11 for contact with the table surface 3 so as toachieve anti-skid effect.

The present invention features on that a plurality of separatedprojecting parts 21 with the same height is integrated with the lowersurface 20 of the skidproof member 2 that contacts with the tablesurface 3. Thus by the contact between the separated projecting parts 21and the table surface 3, the container 1 is set on the table steadily.Moreover, the contact area and adhesion force between the skidproofmember 2 and the table surface 3 are reduced so as to avoid that thecontainer 1 attaches to the table and difficult to pick up. Therefore,the skidproof member 2 not only has anti-skid effect but also preventsattachment of the container on the table surface 3.

Material of the skidproof member 2 is not limited. Generally, silicon orsimilar material is used and made by integration. Cross section of theskidproof member 2 can be round or rectangular with arched corners.Furthermore, there is no limitation on number and interval of theprojecting parts 21 while uniform distribution of the projecting part 21is preferred so as to improve stability of the container 1 on the tablesurface 3. Moreover, shape of projecting ends 22 of the projecting parts21 is not limited. It can be curved or semispheric surface, as shown inFIG. 4, FIG. 12, FIG. 13, FIG. 14, or a smooth surface, as shown in FIG.5.

In addition, the projecting parts 21 is integrated into the lowersurface 20 of the skidproof member 2. While manufacturing, the old moldof the skidproof member 2 is modified by adding a plurality of slotswith shape corresponding to the projecting part 21 on the lower surface20 thereof. Then the skidproof member 2 of the present invention isproduced according to conventional manufacturing processes. Thus thepresent invention has no influence on appearance of the container 1 andthe design of the circular slot 11 on the bottom 10. Besides,manufacturing and assembling of the skidproof members are not affected.

Additional advantages and modifications will readily occur to thoseskilled in the art. Therefore, the invention in its broader aspects isnot limited to the specific details, and representative devices shownand described herein. Accordingly, various modifications may be madewithout departing from the spirit or scope of the general inventiveconcept as defined by the appended claims and their equivalents.
